07 December 2012
Gresham Power Electronics' new eFO600 range of 600W low profile, high power density power supplies comes in a rugged 1U high chassis measuring just 98 x 173 x 38mm It features a universal 85–264VAC input with PFC and is RoHS compliant. The output provides for active load current share and an on-board O-ring diode is provided for N+1 parallel operation.
The primary output voltage features remote sense and may be specified as 12V, 24V, 28V, 32V, 48V or 56V with an optional second output available at 3.3V, 5V, 12V or 24V, up to 5A or 50W maximum. A further option is a 5V standby output.
The Gresham eFO600 meets full international regulatory and EMC approvals (with external line filter), and has a typical full load efficiency of 89% at 230VAC. All models have over temperature protection and system signals and commands, including inhibit (on/off), output fail, input fail and an optional I²C bus output.
Operating temperature range is -40°C to +50°C with linear de-rating to 50% output power at 70°C and MTBF is calculated as 500,000 hours (300,000 hours on 12V version) minimum, per BELCOR 332, issue 6 specification at 30°C.
